vals to receive a positioning slide 17, which is insertable in anyselected one of the slots 15.

A selected number of transversely aligned, symmetrically paired, drillguide holes 18 and 19 are provided in the wing portions 12 and 13,respectively.

The slide 17 supports the fixture A in adjusted position on a corner ofa door 20 as shown in FIG. 2, and, by using a selected pair of the holes18 and 19 in the wings 12 and 13, holes may be drilledin similar, butreversed,

Patented July 4, 196 1 ing screws 25 inserted in a usual manner in theseholes, the pulls will be in matching position.

Referring to the drawings in detail, in the fixture A the front plate 10is of suitable, and preferably light weight material, such as, forexample, aluminum alloy or plastic material. The narrow upper portion 11of the front plate 10 may be integral with the pair of similar,oppositely extending wing portions 12 and 13 at its lower end.

A plurality of similar, and similarly spaced, holes 18 and 19 of a sizeto receive a desired drill 27 therein, is provided in each of the wingportions 12 and 13. Each of the holes in one wing portion, for examplethe hole 18a, is paired with a similarly located hole 19a in the otherwing portion.

The rectangular back strip portion 14 is fixedly secured to the rear ofthe narrow upper portion 11 of the front plate 10, and is centrallyaligned therewith. The back strip portion 14 may be either moldedintegrally with the front plate 10, or may be secured thereto as byscrews 18 (FIG. 2) or a suitable adhesive material, not shown. The sidefaces 29 and 30 of the back strip portion are perpendicular to the rearsurface of the front plate 10 and parallel to each other, and the axesof the drill'guide holes 18 and 19 are aligned to define a plane 31perpendicular to the front plate 10 and the parallel side faces 29 and30 of the back strip portion 14.

The slotted openings 15 through the back strip portion 14 are identicalto each other, and are parallel to the plane 31 defined by the axes ofthe drill guide holes 18 and 19. The lower sides of successive slottedopenings 15 are spaced from the plane 31 defined by the axes of thedrill guide holes by selected measured increments, for example, oneinch. The lowermost slot 15 in the illustrated form A of the inventionmaybe two inches from this line, since door pulls are not ordinarilymounted with their mounting screws closer than that to the top of; adoor.

The positioning slide 17, with its flat, lower face 32, has a shankportion 17a of a size for fitted insertion into any selected one of theslots 15, preferably with a snug sliding fit so that it will not falloutby its own weight. A thicker head portion 17b is provided on theslide 17, which limits the insertion of theslide into the slots 15 tosubstantially the extent shown in FIG. 3. In this latter position of theslide17, the shank 17a projects outwardly from one side of the backstrip portion 14, while the head By manually grasping the head portion17b the slide 17 may be Withdrawn from any slotted opening 15 in whichit may be inserted, and may be reinserted, flat side downwardly, intoany selected one of the slotted openings .15. Thefiat under face 32 ofthe slide 17 will then be located a selected number of inches, or otherselected incrementof measure, up from the plane 31 defined by the axesof the drill guide holes 18 and 19. An index number 33 is providedadjacent each slotted opening 17 indicating'its distance, inthe selectedincrements of measure, from the plane 31 of the hole axes. In using thefixture A it will be assumed that the three pairs of holes 18a, 19a, and18a and 18b, and 18c and are, respectively, one, one and one-half, andtwo inches from the side faces 29 and 30, respectively, of the backstrip portion 14, and that the slotted openings 15 are spaced from theplane 3-1 of the drill guide holes 18 and 19 by increments of one inch,beginning at two inches. It will be further assumed that it is desiredto mount the pair of door pulls 23 and 24 (FIG. 4) four inches down fromthe top, and two inches in from the free edges of the pair of cabinetdoors 21 and 22.

The slide. 17 would then be withdrawn from any other slotted holes, suchas, for example, the one designated by the numeral 2 shown in FIG. 1,and would be reinserted in the slotted hole designated by the numeral 4.The fixture A would then be positioned on one of the doors in the mannershown in FIG. 2, with the slide 17 resting. on the top edge of the door,the side face 30 of the back strip portion '14 pressed firmly againstthe free edge of the door, and the wing portion 13 closely overlying theexternal face of the door. A drill 27 would then be inserted in theoutermost hole 19c, which, as stated previously herein, is assumed to bethe desired two inches from the side face 30 of the back strip portion14. Using this hole 190 as a guide, the drill 27 would be driven throughthe door, thereby drilling a hole in the door. A usual door pull screw25 would then be inserted from the inside of the door through the holethus drilled, and screwed into the door pull 24 in a usual manner. Theother door pull 23 would then be similarly mounted on the other, or lefthand door (FIG. 4), using the corresponding hole 180 in the other wingportion 12. The door pulls 23 and 24 would thus be mounted symmetricallyon their respective doors.

While the fixture A shown in FIGS. 1-3 and 5 may be used for a long timewithout damage providing the drill is inserted in the guide holes 18 or19 before starting the drill, still it may be desirable to face theholes 18 and 19 with a suitable hard material, such as, for example,case hardened steel. In such case a bushing 34 of such material may befitted into the holes 18 and 19. Such reinforcements may be desiredparticularly if the entire fixture A is to be made, for example, ofunitary molded plastic material, which material is usually easily cut byan edged tool.

If it is desired to use door pulls such as that 35 shown in FIG. 6, andhaving two mounting screws, the fixture A would be used as shown in FIG.2, wherein a first hole is drilled with the fixture in its solid lineposition, and a second hole is drilled with the fixture in its brokenline position Aa. Obviously for such use, the slotted openings 15 wouldhave to be spaced apart in increments corresponding to the spacing ofthe screw holes in the door pull 35 to be mounted.

The invention provides a simple, accurate and easily used drillingfixture, which greatly facilitates the mounting of door pulls, and whichmay be carried in a mechanics tool box where it occupies little spaceand is always ready for use.

While I have illustrated and described a preferred embodiment of thepresent invention, it will be understood, however, that various changesand modifications may be made in the details thereof without departingfrom the scope of the invention as set forth in the appended claims.
